Directions in High Efficiency Research and Future Fuel Opportunities

The internal combustion engine will continue to be integral to the transportation of people and goods for the foreseeable future. To reduce environmental impact and improve energy security, many nations are enacting new aggressive fuel economy and emissions standards which are pushing the development of new engine technologies, sensors, and onboard computers on an unprecedented scale. These advances are enabling new high-efficiency combustion modes which blur the historical distinction between spark-ignition and compression-ignition engines, and blend the best characteristics of both to push the boundaries of engine efficiency. Gasoline compression ignition (GCI) combustion is an advanced combustion mode that has received considerable attention in recent years. This presentation will discuss the challenges and opportunities of a wide spectrum of advanced combustion modes under investigation with examples from research at Oak Ridge National Laboratory.

Dr. Robert Wagner is the Director of the Fuels, Engines, and Emissions Research Center at Oak Ridge National Laboratory; a faculty member at the University of Tennessee, Knoxville; and a Fellow of the Society of Automotive Engineers (SAE) and the American Society of Mechanical Engineers (ASME). His responsibilities include the coordination and development of strategic internal and external collaborations at ORNL. Dr. Wagner has been principal investigator on many research activities spanning low temperature combustion, unstable combustion fundamentals, nonlinear controls, thermodynamics, renewable fuels, and emissions characterization. This includes the integration of ORNL expertise in high performance computing, neutron sciences, material sciences, and advanced manufacturing.
